The investigators hypothesize that the post-hospitalized patient status is characterized by subacute and reversible metabolic and hematological changes that, if addressed and treated in a timely manner, would result in a reduced risk for repeat hospitalization. Consequently, a structured quality improvement program, focused on increasing adherence to company wide anemia management policies (ie hemoglobin monitoring within the first 3-5 days post-hospitalization, followed by an appropriate EPO dose modification within the 7 days post-hospitalization), will significantly decrease the risk of hospital re-admission in the 30 days after discharge.
